FS#10253 : mkamsboot v1.0
- Bump version to 1.0 - Add Clipv2 target - Make mkamsboot work as a library (work by domonoky : FS#10185, with a few modifications by me) . Use a macro with variadic arguments for error cases in functions which might error. . Add detailed descriptions to functions exported by the library (in the header file) - modify bin2c.c to produce only one pair of .c/.h files with several files embedded in it - move files needing to be built by an ARM cross compiler into dualboot/ - commit produced .c/.h files (containing nrv2e_d8.S and dualboot.S built for Clip, Fuze, e200v2, c200v2, m200v4, Clipv2) - Write a real README file - cosmetics: indent dualboot.S properly, remove trailing spaces, limit lines to 80 characters - comments: add/correct comments in dualboot.S and mkamsboot.c - move back extract_fw.c to utils/AMS/hacking git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21118 a1c6a512-1295-4272-9138-f99709370657

|
|||
|
||||
A tool to inject a bootloader into a Sansa V2 (AMS) firmware file.
|
||||
|
||||
See comments in mkamsboot.c and dualboot.S for more information.
|
||||
|
||||
Usage
|
||||
-----
|
||||
|
||||
mkamsboot <firmware file> <boot file> <output file>
|
||||
|
||||
<firmware file> is an original Sansa firmware file obtained from the Sansa
|
||||
forums for example : http://forums.sandisk.com/sansa/?category.id=devices
|
||||
|
||||
<boot file> is the code you want to execute (a rockbox bootloader), previously
|
||||
scrambled with tools/scramble utility.
|
||||
|
||||
<output file> is the resulting firmware file which you'll have to copy on your
|
||||
Sansa player. See "Firmware filenames".
|
||||
|
||||
|
||||
Supported models
|
||||
----------------
|
||||
|
||||
Sansa Clip : firmware version starting with "01."
|
||||
Sansa Clipv2: firmware version starting with "02."
|
||||
Sansa Fuze : firmware version starting with "01."
|
||||
Sansa E200v2: firmware version starting with "03."
|
||||
Sansa C200v2: firmware version starting with "03."
|
||||
Sansa M200v4: firmware version starting with "4."
|
||||
|
||||
|
||||
Firmware filenames
|
||||
------------------
|
||||
|
||||
For the firmware upgrade to happen, the firmware has to be named specially:
|
||||
|
||||
clip v2 : m30pa.bin
|
||||
clip : m300a.bin
|
||||
fuze : fuzea.bin
|
||||
e200v2 : e200pa.bin
|
||||
c200v2 : c200pa.bin
|
||||
m200v4 : m200a.bin
|
||||
|
||||
|
||||
Dual-Boot
|
||||
---------
|
||||
|
||||
The purpose of this program is to provide dual-boot between the original
|
||||
firmware and the new (rockbox) firmware.
|
||||
|
||||
By default the player will boot into the new firmware.
|
||||
|
||||
To boot into the Original Firmware, you need to press the Left key.
|
||||
***Note : on the c200v2 you need to press the Right key.
|
||||
|
||||
The player will boot into the Original Firmware as well if it is powered up by
|
||||
inserting an usb cable.
|
||||
***Note : on the m200v4 powering up by usb will cause booting into the new
|
||||
firmware
